A transaction goes into the mempool as an unconfirmed transaction, and then when a miner includes the transaction in a block, it is moved from the mempool to the blockchain as a confirmed transaction.

The address link you provided shows 2 unconfirmed transactions at 120 sats/B. So these are in the mempool, but could take upto 7 hours to confirm according to the bitcoinfees website estimate.

If your transaction is not showing as an unconfirmed transaction, then we would need a transaction ID to look at. Different network nodes have different mempool settings, so it may show on some sites but not others.

My only concern is that this would NEVER confirm and that the sender had scammed me. If there's no chance of that happening then this thread can be closed.

I can't say that there is no chance it will never confirm. If demand for blockchain space suddenly increases, newer transactions with higher fees will push your transaction down the queue. After three days, mempools on the default settings will start dropping the transaction. Then your sender could try and double spend it elsewhere. Likewise, if the mempool exceeds the configured size of a node, it will start dropping it from the mempool. Things don't look that bad at the moment, so it probably will confirm within 24 hours.

If you look at both those transactions both of them have unconfirmed inputs. This means whoever sent the bitcoin used a wallet like blockchain.info which lets you spend unconfirmed inputs. It might take a few days for everything to get sorted as the earlier transactions have to confirm first before the later ones can. You can also use the ViaBTC transaction accelerator tool (Google it) to get the earlier transactions confirmed before they are dropped. Everyone needs to move away from that crappy blockchain.info wallet and others that let you spend unconfirmed inputs.

Does not look like the transactions do have unconfirmed inputs to me, so either I'm looking at the wrong ones or getting confused.Unconfirmed transactions in the mempool have climbed again (41,000+, 81+MB), so these transaction may take some time to confirm.

When looking at the links, I assume the wallets that are showing output next to them are the 2 smallest wallets owned by his blockchain that could be used to make the total of .26 for one transaction and .09 for another. I assume the leftover BTC is going back to the senders other wallets?

When I use the accelerator I get error "Submissions are beyond limit. Please try later." and I'm copying exactly as 87becfffd4e1e6b93f84ea4fd9dac990399b3d17d9448061fa7e05724b277d47 and 21869ca0ea465c77b06768f0414edf94585d69fdde9a25be6dd58cb4820f7a5c

If using the viabtc accelerator, there are only so many open slots per block they find, and they fill up pretty quick. Keep trying as soon as they find a block!
